SQL trigger using raise_application_error thows error. up vote 0 down vote favorite I have a few things of code I need help debugging but I feel that if I can get one of them running i'll be able to get the rest(oh how i hope). create or replace trigger minimumwage before insert or update on Employee for each row begin if :new.Wage < 7.25 sqlerrm then raise_application_error('-20000,Pay is below Texas minimum wage!'); end if; end; / I'm trying to do this on a table ran on my school's server through sqlplus if that helps. sql plsql sqlplus share|improve this question edited May 8 '13 at 20:46 Goodwine 92711125 asked May 8 '13 at 20:02 user2363828 312 1 What issue are you having? –zimdanen May 8 '13 at 20:05 Warning: Trigger created with compilation errors. was the issue –user2363828 May 8 '13 at 20:53 i fixed all of my errors on my other triggers except for one that involved count overall i'm really happy i posted this question < 3 –user2363828 May 8 '13 at 21:25 1 Run show errors and show us the real error message. –a_horse_with_no_name May 8 '13 at 22:41 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted When you're getting an error, it's always helpful to specify what error. There is a syntax error in the raise_application_error call in your trigger. That procedure takes two arguments, a number and a string. You are passing in a single arg

partitions every day and add partitions. My question is about the exception section. Do I have to give specific exception conditions to handle the erros which are possible while dropping and adding partitions, or should I leave it by just giving the when others then exception, or should I leave it alone by not giving the exception section at all. what are the possible erros which can occur while trying to create a partition and trying to drop a partition. 2. The use http://stackoverflow.com/questions/16449225/pl-sql-trigger-using-raise-application-error-thows-error of pragma exception init is very clear, but Why do you have to use a raise application error. Can I just use a regular exception, and raise it when I require to. I dont see the specific use of raise application error. what is the advantage of raise application error over a regular exception which you declare in the exception section and use it. (the only advantage seems to be that you can assign a number(20001 to 20999) to the error.) correct me if https://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:1155066278457 Iam wrong. and we said... 1) A when others is almost always a BUG unless it is immediately followed by a RAISE. The point of an exception block is to catch exceptional conditions you are EXPECTING, handle them gracefully and continue. For example, lets say you have a procedure that will either INSERT a new record or UPDATE an existing one depending on whether or not it exists. You could code: begin insert into t ( columns.... ) values ( values ..... ); exception when dup_val_on_index then -- record already exists, lets update it update t set .... = .... where ....; end; Now, if that was coded: begin insert into t ( columns.... ) values ( values ..... ); exception when dup_val_on_index then -- record already exists, lets update it update t set .... = .... where ....; when others then null; end; that would be a bug. The when others would fire upon some spurious -- un-expected error and the record would be neither added nor updated. It would be skipped. Same with your routines, if you have a when others -- and don't do anything meaningful in it (eg: email yourself a notification that it failed, log a message using utl_file or an autonomous transaction, etc -- it is an error that will go undetected. I truly wish we didn't even support WHEN OTHERS. You should only catch the exceptions you are expecting and can do something about. Let the others propagate out so y
